Electric Vehicle Charging Station M2M Applications
Electric vehicles like electric cars, electric motorcycles and electric scooters are becoming a more a popular type of transportation. They are usually quieter and mechanically simpler than internal combustion engine vehicles. The cost of recharging is much less than gasoline; it is like paying 60 cents per gallon of gas. Electric vehicles are typically directly powered by external power stations that are powered by stored electricity. Electric vehicle charges may take up to a few hours for normal everyday usage.
CAN is a communication protocol that is commonly used in the Automobile Industry. Electric vehicles can communicate with charging stations through CAN to Wi-Fi converters like I-7540D-WF. Serial to Wi-Fi converters like M2M-711D can bring the charge pump to communicate with the electric vehicle. Cellular modems like GTM-201-3GWA can allow electric charge pumps to communicate back to a central location and can report pump usage or problems with the pump.
CAN converters allow vehicles to communicate with different types of devices and networks. They translate CAN protocol to another type of protocol other devices and networks can understand. I-7540D-WF is a CAN to Wi-Fi converter which supports the wireless transmission of CAN data between various CAN networks or allows communication between a CAN network and a WLAN network according to 802.11b/g standards. CAN converters like I-7540D-WF are set up with a software utility, support encryption and can be used in point to point or point to multi point topologies.
Serial to Wi-Fi converters allow pump stations to communicate with electric vehicles by allowing serial data to communicate with the WLAN network. M2M-711D supports data tunneling between two RS-485 or RS-422 serial devices through virtual COM ports. They support a wireless transmission distance up to 100 meters, support encryption and are set up with a software utility.
Cellular modems like GTM-201-3GWA allow pump stations to report back to a central server. The pump and alarm data can be collected and stored for analysis. They can also allow the charge station to send electric vehicle operators an SMS text message when the vehicle is done charging. GTM-201-3GWA supports 850/900/1800/1900 Mhz and 3G networks.
M2M devices allow electric vehicles to communicate with charge stations and charge stations to communicate back to central servers. Machine to Machine solutions help make our lives simpler and more convenient. Text message notifications help drivers to know exactly when their vehicles are done charging so they can more easily make it to their next destination.
